Environmentally friendly technology for the treatment of surface runoff from industrial sites

Summary

The issues related to the collection and treatment of surface runoff from the territories of industrial enterprises are stated. The analysis of the technologies for surface runoff treatment showed that the applied process flow schemes, generally, did not produce the required effect and were uneconomical. In addition, the technologies and equipment often do not provide for the utilization of wash water and sludge generated during the treatment of surface runoff. As a result, raw surface runoff containing suspended solids, oil products and other pollutants enters water bodies and produces a negative impact on the ecosystem of water bodies, public health and safety. In this regard, improving the technologies of surface runoff treatment to achieve high efficiency at minimal costs is a most urgent task. The characteristics of the composition of surface runoff from industrial sites are given through the example of a CPP facility in Novosibirsk. Surface runoff treatment methods are considered. The way of improving the technologies of surface runoff treatment with the use of structurally new treatment facilities, increasing the efficiency of chemical treatment and utilization of sludge is determined.
